Tim Zigler, left in inset, and Brandon Foshee formed Fauxsee to sell Roboglasses, a device that helps the visually impaired avoid head and upper body injury. The original Roboglasses prototype (below), designed by Tim Zigler, was simply a pair of sunglasses with parking aid sensors attached.

Ten years after losing his sight, Brandon Foshee and his brother-in-law Tim Zigler are turning tragedy into business with the development of "Roboglasses," a product intended to keep the visually impaired aware of their surroundings and reduce injuries.
